Employing the local skilled labor for doors, windows and other finishes over buying readymade items with high embodied energy.

The wood used for doors and windows came from trees destroyed after the 2004 tsunami.

Renewable energy sources

An Earth Cooling Tunnel was built. A fan pushes hot air in a pipe which runs about 5 m deep and 35 m underground: first 15 m long at the bottom of the rainwater harvesting tank and then 20 meter in the ground. The system cools the air by heat exchange which is blown into residential units.

Water management

Roof rainwater is harvested in an underground water tank and reused for gardening and to cool the air for the Earth Cooling Tunnel.

Surface rainwater is harvested in a percolation pit in order to recharge the water table.

Earth management

The soil dug from the rainwater harvesting tank was used to make stabilized earth blocks for the building.

The Auroville Earth Institute links the ancestral tradition of raw earth architecture with the modern technology of stabilized earth.

Stabilized raw earth can be used as a building material from foundations to roof.

Building with earth is an efficient way to use local resources, revive the local skills and the building tradition. The role of the architect is also essential in this process as he should be at the service of the society and its people. The architect should not be only a designer but also a builder and he should be able to build with people so as to give them the means to build their own habitat themselves.

Architectural consultancy: the architect team of the Auroville Earth Institute can design and prepare detailed plans for anyone wishing to build their house using Compressed Stabilised Earth Blocks (CSEB). The Auroville Earth Institute is an architecture firm that manages projects from the conception stage to their construction. The institute has received 2 international prizes and 11 Indian prizes.

Training: The Auroville Earth Institute regularly organizes two weeks long training courses. They are open to all engineers, architects, technicians, masons and students who wish to learn how to produce and build with Compressed Stabilized Earth Blocks (CSEB) and other earth techniques. Specialized training courses in the analysis and construction of arches, vaults and domes are also offered. These construction techniques are an alternative to the use of reinforced concrete.

Research: Since the very onset the Auroville Earth Institute has conducted researches on various stabilised earth technologies and developed composite techniques made of CSEB and reinforced cement concrete. Since 1995, the Institute has developed a construction technique for disaster resistance with hollow interlocking CSEB. This technology has been approved by 3 governments.

Technology transfer: the Institute is frequently called upon to conduct consultancies to disseminate earth architecture and technologies. Our team worked in 32 countries all over the world.

Soil testing: we provide soil testing for those interested in building with earth.

Block testing: test of blocks with a compression test machine. Both dry compressive strength and wet compressive strength are available. By following a strict procedure we are able to give reliable results.

CSEB order: production of Compressed Stabilized Earth Blocks (CSEB) for the Auroville area.

Auram equipment: A wide range of earth construction equipment has been researched and developed and is sold today worldwide. This equipment is manufactured by the workshop Aureka.
